We examined a homogeneous group of 116 patients with laryngeal and hypopharyngeal carcinomas, treated with surgery followed by radiotherapy according to the conventional procedure. The tumors occurred in the larynx in 88 cases (75.86%) and in the hypopharynx in 28 (24.14%); correlations between overall survival and disease-free survival on the one hand, and clinical and histological parameters on the other hand were established with a multivariate analysis using the Cox method. After 5 years 75.86% of the patients were alive. This variable was negatively influenced by pN (pN0 89.8%, pN1 76.2%, pN2 69%); pT (pT3 82.5%, pT4 62.5%), by vascular embolization (90% of patients alive with no vascular embolization versus 69.7% with vascular embolization), by the grade of peritumoral inflammation (64.3% of patients alive with slight peritumoral inflammation, 69.2% with medium-grade inflammation and 87.3% with strong inflammation), and finally by a great number of plasma cells and few granulocytes; 78.44% of these patients remained disease-free. This variable was negatively affected by pN (pN0 91.8%, pN1 76.2%, pN2 60%), patients' age and extracapsular spread (85.5% of disease-free patients with no extracapsular spread, vs. 51.55% with extracapsular spread); and positively influenced by basal cell differentiation (95% of disease-free patients versus 71.8%). Overall and disease-free survival rates which differed at the beginning, coincided after two years because of local recurrences. On the basis of these results we conclude that the correct assessment of morphologic variables should be considered as a useful tool for treatment planning.

Abstract

We examined a homogeneous group of 116 patients with laryngeal and hypopharyngeal carcinomas, treated with surgery followed by radiotherapy according to the conventional procedure. The tumors occurred in the larynx in 88 cases (75.86%) and in the hypopharynx in 28 (24.14%); correlations between overall survival and disease-free survival on the one hand, and clinical and histological parameters on the other hand were established with a multivariate analysis using the Cox method. After 5 years 75.86% of the patients were alive. This variable was negatively influenced by pN (pN0 89.8%, pN1 76.2%, pN2 69%); pT (pT3 82.5%, pT4 62.5%), by vascular embolization (90% of patients alive with no vascular embolization versus 69.7% with vascular embolization), by the grade of peritumoral inflammation (64.3% of patients alive with slight peritumoral inflammation, 69.2% with medium-grade inflammation and 87.3% with strong inflammation), and finally by a great number of plasma cells and few granulocytes; 78.44% of these patients remained disease-free. This variable was negatively affected by pN (pN0 91.8%, pN1 76.2%, pN2 60%), patients' age and extracapsular spread (85.5% of disease-free patients with no extracapsular spread, vs. 51.55% with extracapsular spread); and positively influenced by basal cell differentiation (95% of disease-free patients versus 71.8%). Overall and disease-free survival rates which differed at the beginning, coincided after two years because of local recurrences. On the basis of these results we conclude that the correct assessment of morphologic variables should be considered as a useful tool for treatment planning.
